CONST RUCTING TOWERS.

SPECIFICATION formingpart of Letters Patent No. 279,422, dated June 12, 1883.

To aZZ whom it may concern.-

Be it known that I, EDWARD J. OBEIRNE, a citizen of the United States, residing at Evansville, in the county of Vanderburg and State of- Indiana, have invented certain new and useful Improvements in Oonstructin g Towers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form. a part of this specification.

Figure 1 of the drawings is a representation of a tower. Fig. 2 is a side view of a portion of the same. Fig. 3 is a cross-sectional view Figs. 4 and lime side views of part of the post, and Fig. 6 is a plan view of the tower. i

This invention has relation to the construction of towers for the display of electric or other lights in harbors or in navigable streams where light-houses are commonly used; and it. consists in the construction and novel arrangement of tower-secti ons composed of posts, girts, and braces, made of wrought-iron, and of fittings and couplings of malleable iron, and connecting-bolts, as will. be hereinafter more fully described, and particularly pointed out in the claims appended.

The object of this invention is to construct a strong, durable, and cheap tower for displaying electric or other lights where needed in the interests of navigation or for other purposes; and in order to accomplish the object I build the top section first, raise it to the re quired height, and then build the next section beneath it, and continue to build successive sections, raising the structure until all of the sections have been completed and joined and rested on a suitable foundation prepared for the structure. 7

Referring to the accompanying drawings, a designates the foundations or supports for the tower. These may be constructed in any wellknown manner. The tower is preferably constructed in triangular form; but it may be c011- Application filed J annary 18, 1883.

termed staniron, and are of wrought iron, as are also the girts c andbraces (Z.

The couplings or sleeves e are of malleable iron, and are provided with sockets ff for the reception of the ends of the girts c, inclined sockets and the ends of the diagonal braces In securing the sleeves to the posts b in the first instance bolts 7c are employedto hold the sleeves e in place; but after the girts and diagonal braces are in place they coact to hold the sleeves in place on the posts.

Heretofore tubing, or what is commonly termed gas-pipe, has been used in structures of this character; but a great objection to employing posts of this kind lies in the fact that where the greatest strength is required threads the girts to the posts, or from girt to girt, or post to post, as safety may require.

In constructing the tower I prefer to follow the plan herein after described, although others may be adopted which will prove equally ad- At each postor corner I erect a twenty two foot derrick, with gearing and tackle attached, after which the first or top section is built upon the ground, then stood on end, and four guy-ropcs attached to the top of the tower. The lower tackle blocks are then hooked to the l ower corners or base of the tower, and the tower-section is raised sixteen feet by turning the crank oft-he derrick-gearing. The second sccti on from the top isthen built beneath the first section, the tackle overhauled and attached to the base of this section, and the derrick again operated to raise the two sections, and section after section is thus added until the structure is completed and rested on its foundation and secured in place. The guyropes, which are of the best manila, are fastened to posts sunk in the ground at a suit-able distances from the tower, to correspond with its height when finished, and are increased in size at the completion of everyhundred feet of shown in the drawings, and may extend from the tower by four additional guys. These guys are all removed when tower is completed.

Having thus fully described my invention, what I claim as new, and'desire to secure by 5 Letters Patent, is

1. In a tower for electric and other lights, the combination, with the star-iron posts I), of the girts and braces, and the sleeves provided with the horizontal and inclined sockets secured in place by bolts passing through the sleeves and posts, substantially as specified.

2. In a tower for electric and other lights or for other purposes, the star-iron posts I), in combination with the socketed sleeves and their securing-bolts, substantially as specified.

In testimonywhercof I. affix my signature in presence of two witnesses.
